No, I've not one of these basses, but from the photos I see on t'web, I'd think it even more odd to have one's arm rested there, whilst playing, at least..! It's in the inside curve of the lower bout, and so quite protected, unless one uses the bass body as an arm-rest, and even then...
You're very experienced in acoustic basses (far more than I, that's for sure..!); from what I see in your previously-posted videos (I'm watching 'In My Life' again right now, with much pleasure...), there'd be no problem.
Hope this helps (but doubt it...). Also glad to see you're considering an acquisition; I'll assume things are looking up for you..?
